SPECIFICATION forming part of Letters Patent No. 629,554, dated July 25,1899.

To @ZZ whom t may concern:

Be it known that I, FRANKLIN P. EAs'rMAN, of the city of New York,borough of Manhat tan, in the county and State of New York, haveinvented a new and Improved Dumping- AScow, of which the following is afull, clear, and exact description.

The invention relates to dumping-scows, such as shown and described inthe Letters Patent of the United States No. 359,012, granted to me onMarch 8, 1887.

The object of the present invention is to provide a new and improveddumping-scow arranged to facilitate the dumping of all kinds ofmaterial, especially house and street refuse and the like.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is tobe had to the accompanying drawings, forming a part ofthis specitication, in which similar characters of reference indicatecorresponding parts in all the iigures.

Figure lis a plan View of the improvement with parts broken out. Fig. 2is a side elevation of the same with parts broken out and parts insection. Fig. 3 is an enlarged transverse section of the improvement onthe line 3 3 in Fig. l. Fig. 4 is an enlarged face View of part of theimprovement, showing the locking 'device for the side; and Fig. 5 is atransverse section of the same on the line 5 5 in Fig. 4.

The improved dumping-scow is provided with a suitably-constructedframework A, to which are attached the bottom Band the inclined floorsO, forming a peak-shaped section extending centrally and longitudinallyfrom one end D of the scow to the other end D', as is plainly indicatedin Figs. l and 2. One or more bulkheads E may be arranged on the` sideof the scow to give the desired strength to the structure.

On the lower outer end of each floor O are arranged pivots F, on whichare hung arms G, normally extending vertically to support at their upperoutwardly-curved ends the sides II, extending from one end D to theother, so as to form with the ends and the inclined floors compartmentson each side of the scow. The connection between the arms G and thesides II is by means of pivots, so that when the arms G are swungoutward, as indicated, in dotted lines in Fig. 3, then the sides II movewith the arms and hang verti cally therefrom, owing to their Weight, topermit the contents of the scow to slide down the inclined bottom O intothe surrounding water.

In order to keep the sides H and arms G in a vertical or closedposition, as illustrated in full lines in Fig. 3, I connect the sideswith a pair of transversely-extending ropes or chains I, extendingthrough openings in the door O to the inside of the framework andpassing over fixed bearings or guides J to then connect with alongitudinally-extending rope or chain I', attached to the piston-rod ofa hydraulic or other ram K of any approved construction and located ator near one end of the scow. When the piston of the ram is in anoutermost position, the sides H are closed, and when the motive powerfor the ram is permitted to escape therefrom then the sides H and thearms G are free to swing outward by the pressure of the load restingagainst the said sides H.

In order to lock the free or lower ends of the sides H in place whileloading the scow and transporting it to a place of discharge, I providelocking devices L, each comprising a hook L', fulcrumed on the lower endof the corresponding door O and adapted to be en gaged by alocking-plate L2, having an elongated aperture through which is adaptedto pass the outer end of the hook. The lockingplate L2 is fitted toslide vertically in suitable bearings L3, (see Figs. 4 and 5,) attachedto the corresponding side H, and the said plate is hung on a rope L4,extending upwardly and passing over a pulley L5. The several ropes L4for both sides connect with a rope L, leading to a capstan, windlass, orother similar winding apparatus i'or windin g up or unwindin'g the ropeor chain L6 to raise or lower the several plates L2 simultaneously. Thehook L of each locking device also extends through an opening in thecorresponding side I-I and is adapted to normally rest on a projectionL7, attached to the corresponding floor O. When the side I-I is in anopen position, the hook L rests on the projection L7, and when the armsG swing inward and carry the side along then ICO the hook passes throughthe opening` in the Vside and that of the locking-plate L, and

when the side has reached its innermost position then the rope L iswound up on the windlass or capstan N, so as to draw the plate L2 upwardand swing the hook L into alocking position to securely fasten the freeend of the side -in place. Now it is evident that when the sides areclosed the scow can be readily loaded with Ahouse and street refuse `andthe like and then towed to the place of dumping, and when the place isreached the operator unlocks `the sides I-I by reversing the wiudlass Nto allow the rope L6 to unwind and the plates L2 to drop and disconnectthe hooks L from the sides H. The sides H are now free to swing outwardwith the arms Gr as a fulcrum, and the operator now permits the motiveagent in the ram K to discharge, so that the arms G are free to swingoutward, carrying the sides H with them into the position indicated indotted lines in Fig. 3, so that the contents of the scow can readilyslide down the inclined floor C into the surrounding water. By thearrangement described no obstruction in any shape or form is left forthe refuse to cling to after the sides H are opened, soA that a completedischarge of the entire load takes place.

It is understood that house and street refuse when loaded, for instance,on a scow of the construction shown and described in the, pat-ent abovereferred to is liable to cling tosides, and arms ou which the sides arehung, said arms being pivotcd tothe scow, substantially as shown anddescribed.

2. Adumpiug-scow, provided with movable sides, arms on which the sidesare hung, said arms being pivoted'to the scow, and a locking device forlocking the sides in place on the scow, substantially as shown anddescribed.

3. A dumping-scow provided with an inclined floor, arms pivotcd at ornear the lower, outer ends thereof, and a side hung on the upper ends ofthe said arms and adapted to form a compartment with the door and theends of the `scow when closed, substantially as shown and described.

4. A dumping-scow provided with an `in-V clined floor, arms pivotedatornear the lower, outer ends thereof, a side `hung on the `upper ends ofthe said arms and adapted `to form a compartment with the licor and .theends ,of the scow when closed, and means for permitting a swingingmotion to ,the said arms to allo7 the sides to open orclose,'substantially as shown and described.

5. A dumping-scow provided with an inclined Iioor, arms pivoted at ornear the lower, outer ends thereof,a side hung on the upper ends of thesaid arms and adapted to form a compartment with the `iioor and the endsof the scow when closed, means for .permitting a swinging motion to thesaid arms to allow the sides to open or close, anda locking device underthe control of ,the operator, for fastening the lower, free end of theside to the scow at the lower outer end of the `correspondin g floorthereof, substantially as shown and described.
